I'm guessing you have a subscription to Nintendo Power, too, eh?
That is definitely a good sight to see. I practically had a heart attack when I saw Dora the Explorer on the top-selling list, and at Number 1! I thought about all of the good games out there for the GBA and then looked at the DtE game. Just as NP said, "Really?"
I'm glad the GBA is not totally dead yet, because it still plays old GB and GBC games. The DS can't even play GBC games, as far as I've heard. But, a lot of the newest and the best games are coming out for the DS, so it's good to have both if you still enjoy, say, Pokemon Red but would like Pokemon Mystery Dungeon: Blue Rescue Team.
